Dear Sir,
You are welcome to respond to me in French.
I am sorry to have to say that your letter was incomprehensible at one
point. namely where you said :
". What's the best way to participate, with a demo, a presentation?"
I would like to know where you got my name and I would not mind you sending
me information. If I get a chance I will look at your page later today.
Thank you for your note,
Sincerely,
Vaughn Ohlman

letter with "hi there".
